WebHere we demonstrate a flow cytometer for the obtaining of high-content 2D light scattering patterns of single cells. In our flow cytometer, single cells are flowing in a hydrodynamic focusing unit and their 2D light scattering patterns are recorded via a long working distance objective by using a high-speed complementary metal oxide ... WebHydrodynamic focusing behavior is characterized by two fluids coflowing at different velocities inside a micro-flow cytometer. In this study, a two-fluid model has been established to describe the flow transport behavior and interaction of sample and sheath fluids. The analysis treats the sample and …
WebHydrodynamic focusing is a well known phenom enon in the area of fluid mechanics thanks ... However, the first non-academic microfluidic application of hydrodynamic focusing was in the area of flow cytometry, a technique for counting, examining and sorting microscopic particles suspended in a stream of fluid. Hydrodynamic focusing, … WebIn flow cytometry, hydrodynamic focusing is the process aimed at solving hyperbolic velocity that causes cells/particles to move in a seemingly random manner (unfocused). Typically, this (random movement) occurs before the sample enters the flow chamber. Here, cells/particles in the fluid suspension (sheath fluid) move in a random fashion and ...
